PIVOT-LIGHT.

Be it known that we, [WILLIAM F. GREEN and Crmnnns W. .LINEKER, citizensotthe United States, residing at Modesto, county of Stanislaus, andOakland, county of Alameda, State of California, respectively, haveinvented certain new and useful Improve- ..ments in Pivot-Lights, ofwhich the follow-.

ing-isaspecification.

This invention relates to automobile lamps 5 a311d has special referenceto apparatusconnectlng the lamps with the steering mecha- .nisin' sothat the lamps may be turned to throw the light in conformity with thecurves followed by the machine in changing its course this. inventionfor turning the lamps. Fig.

Theinvention has for its object to provide an improved apparatus of thiskind by means of which both lamps'may be simultaneously turned as thefront axle is turned by the steering mechanism, and also so that one ofthe lamps may be turned independently of the other and moved so as tothrow the light in any. desired direction.

Referring to the accompanying draw ings':-Figure 1 is aplan view of aportion of a device for turning thelamps. 2 is andetail viewin elevationof a device shown in Fig. 1 ,with the casing removed and the upperportion of the device in elevated po- -Q-Sli2l01l. Fig. 3 is an enlargeddetail view in vertical section of the device shown in Fig.

2 with the same closed. .Fig. dis a plan view of a portion of anautomobile with the mechanismconstructed in accordance with 5 is a sideview of the front end of an auto- -1i1obile showing the apparatus forturning clined'portion 2 which fits upon the top of a spring 3, of anautomobile 4: and is detachably secured thereto; in any suitable manner.The casting 1 has projecting from its top and formed integral therewitha cylindrical casing 5 having a flange 6 at its bottom.

'Seated on the flange 6 is a cylindrical member7, secured rotatablyupon'thecasing 5.

Patented time 27, 1911.

The member 7 is formed with V-shaped recesses 9 opposite each other inwhich are seated V-shaped projections 10 of a second cylindrical member11, and vertically slidable on the casing 5 and surrounding the members7 and 11 is a thin cylindrical shell or casing 12 which is fastened tothe lower member 7 by means of a set screw 13 and has its upper endprojecting into a cylindrical slot 14 in the upper member 11. The lowermember 7 of one of the lamp supports is-p-rovided with two arms 14 and15 projecting at a rightangle to each other and the other member 11 isformed with an arm 16 projecting in alinement with the arm let and ataright angle to the arm 15. 7

Within the casing 5 is mounted a vertical bolt 17 having a flange 18 atits lower end. .Mounted above said flange 18 on the bolt 17 is acircular steel washer 1'9 and between the washer l9 and the flange 18are located balls 20 forming ball bearings. The upper end of the casing5 is closed by the disk 21' upper end of the member 11. Mounted. on

the upper end of the bolt 17 and clamped against the top of the member11 by means of a nut 24: is the pivotal portion 25 of the bracket arms26 in which is mounted the lamp 27. Mounted on the bolt 17 within thecasing 5 is a coil'spring 28 which is placed therein under considerablepressure, and has one end fastened. to the steel washer 19. It willbeseen that by means of this construction that as the arm 16 of the memberll-is pulled to cause the member 11 to rotate and by reason of the.tapering projection 10 seated in the taperihg recess 9 will be raised bythe tapering projection 10 on the incline of the opposite taperingrecess 9. In this movement the friction is relieved by the ball bearingshereinbefore described in the casing 5 and in the upper end of themember 11. This rotary movement of the-member 11 causes the'1amp'27 tobe turned at an angle, and the coil spring 28 having been put underincreased'tension by said movement when" the pull on-the arm 15 isreleased reacts to automatically move the member 11 back to its normalposition and thereby bring the lamp 27 to normal position as shown inFig. 4. The arm 15 projecting from the member 7 extends rearwardly fromthe lamp and the end of the arm 15 is pivotally connected at one end toa rod 29 the other end of which is pivotally connected to an arm 30which extends rearward from a rotary member mounted on a support 32secured to the spring 3 the rotary member 30 carrying the arms 31 of thelamp 32.

The lamps are turned in unison by means of a rod 32 pivoted at one endto the end of the arm 14 and connected'to an arm 33 of the regularsteering gear. The rod 32 is made in two sect-ions which are heldtogether by a sleeve 34. One 'portion'of the rod 32 is permanently fixedto the endof the sleeve 34 and the other portion of the rod projectsinto the sleeve 34 and is fastened by means of the set screw 35. Thesleeve 34 is of such a length that during the day the set screw can beremoved leaving the movable part of the rod free to work back and forthby the action of the steering gear without movingthe lamp.

Pivoted to the arm 16 and projecting from the rotary member 7 is a rod36 which extends through a sleeved bracket 37 on the frame of themachine, and is formed in two parts connected by the sleeve 38, one ofthe parts of said rod terminating in the handle 39 located near thesteering mechanism. The sleeve 38 which is shown in detail in Figs. 6and 7 consists of a hollow cylindrical shell containing two longitudinalgrooves 40 and a transverse circular groove .41. The movable portion '36of the rod.

36 has its end projecting into the cylindrical shell forming the sleeve38 and is provided with pins 42 which slide in the grooves 40. Theotherportion 36 of the rod 36. is fastened in an suitable manner totheend of the sleeve 3 When it is desired to couple the twoportions of therod 36, the movable portionf36 is pushed into the sleeve until the pins42 arrive at the.

circumferential groove 41 when the rod is given a turn and the pins 40are brought into engagement with the groove 41 and thereby fasten themovable portion of the rod in the sleeve 38. e

It will be seen that by means of the construction hereinbefore set forththat the lamps are mounted on two rotary pedestals and are connected soas to rotate in unison and turn the lamps in the same direct-ion. Thisisaccomplished by means ofthe rod 32 connected with thesteering-mechanism.

projecting from the upper part of the ped-- estal only operates thelamp- 27, since it causes only the upper member 11 of the pedestal torise and turn.

Having described the invention, we claim 1. In an automobile or similarvehicle, a pair of lamps, rotary pedestals on which said lamps aremounted, each of said pedestals having an arm, a connecting rodpivotally connected to the arms of said pedestals, a second arm on oneof said pedestals having a rod connecting said arm with thesteering-mechanism of the automobile and formed in sections one slidablefrom the other, one of said pedestals being formed with two rotarymembers and one of the lamps being mounted on one of said rotarymembers, an arm projecting from said rotary "member, and a rod pivotallyconnected to said arm and extending to a point adjacent to the steeringwheel of the automobile.

2. In an automobile or similar vehicle, two rotary pedestals at thefront of the machine, each having rearwardly extending arms, a rodpivotally connected at its ends to said arms, one of said pedestalsbeing formed withtwo rotaryv members, one of which is adapted to'rideover and be lifted up by the other as it is rotated, one of said lampsbeing mounted on saidvertically movable member of said pedestal, a rodconnecting the lower member of saidpedestal with the steering gear ofthe machine and formed in two parts. detachably connected together, anda rod connected with the upper movable member of the pedestal andextending to a point adjacent to the steering wheel.
